Comparing Book Search engines

Greg Notess

Looking at what is freely available online
Looking at it like a new HUGE database of searchable written material

Ref q.
Forgot to get full citation after returning book.
Go to amazon and pull up the page

Amazon’s search inside the book
A9
Google book search
Open content alliance
Individual publishers’ initiatives
Open web

Issues w/

Scanned books
OCR quality varies
Full content scans

Full text searching of books
New information source for searchers
Searching, not reading
Think about potential uses
Limited access, but full (?) search

A9 and Amazon
Both can search inside the covers
A9: check books box
Search inside vs. look inside
Currently published books
Including reprints

In amazon – default proxcimity search ? unknown
Amazon
Limit to books database
Look for search inside or look inside image

Now there are exerpts in results lists
And you can click on the see more for the amazon reader
Amazon viewer
Purchase, annotate etc.

Example : glacier panorama look at excerpt pg 16 – garbage

A9
Check books database
Larger retrieval set
“see more references to…”
leads back to amazon
“phrase searching works in both”

The Google books
“the aim of Google Books search is to help you discover books not read them cover to cover”

scan books from publishers
or electronic copies from publishers
agreements with publishers
no agreement=not included
unless part of Google books initiative (library)
Old, out of copyright
Example:
Books and culture by mabie

1923 to present
considered under copyright
but look at current population reports
not good bibliographic record
so gov docs that are available free are not through google books

Limited access with google account
Sample pages
Snippet view
Full view
No preview view

Links to book stores/shopping sites sometimes
Links to open WorldCat
Doesn’t work well if the metadata is poor

The Umich option
Google scans in mirlyn
Mirlyn.lib

Open Cintent Alliance (OCA)
Announced, live later this year?

Internet archive
Universities
http://openlibrary.org
nice interface and flipping pages

Google& Amazon
Both can have old books
Amazon reprints

To find specific books
Check a9, google books, oca
Search open web
Check publisher sites, Ebrary

Search phrase from the content of the book on the open web, you might have some luck.

Or
Intitle:”index of”

National academies press
Offers pdfs of books
e.g. diataries
